Question

1. The line passes through (-7,5) and (-8,13)

answer must be written in slope imtercept form.
2. the line passes through (15,1) and (0,-4)​

Answer 1

1. Find slope
(Y2-y1)/(x2-x1)
(13-5)/(-8+7) = 8/-1 = -8
y = -8x + b
5 = 56 + b, b = -51
Equation: y = -8x - 51

2. (-4-1)/(0-15) = -5/-15 = 1/3
y = 1/3x + b
Now do the rest on your own
